Whenever I press 'print', Firefox hangs repeatedly for ~15 seconds. After ~15s it will respond again for ~4 seconds, before hanging again for ~15s.

I've tried running in Safe mode: same problem.

I've tried reinstalling Firefox: same problem.

I do not have this problem in Chrome.

Has anyone else solved this problem? Please can anyone help?

Thank you! David

Hello,

I love Mozilla Firefox thus am asking this.

Why is graphics performance worse in Firefox than it is on Microsoft's Edge and Google's Chorme browser?

Is it a matter of settings or what?

I have a AMD Ryzen 5 3400GE APU which is very capable of decoding 4k@60 VP9, but when I try watching Youtube videos in this video settings on Firefox, the frame reproduction isn't smooth. I don't have that problem with Chrome and/or Edge.

The video in question is the following:

https://www.youtube.com/watch?v=-Wo3aJjwTlA

PS: not sure why but some 4k@60 VP9 videos on Youtube lag more than others.

Hello,

This issue seems somewhat unique. Using Firefox on 85.0.1 64-bit (but existed for a while) on Ubuntu 20. My laptop is a dell Inspiron with an nvidia GeForce MX250 and driver version 450.102.04 (but, again, this problem existed on earlier drivers). I dual boot Windows 10 on this laptop and use firefox there, but do not have any issues there.

Sometimes Firefox will just start unloading pieces of the web page. It's not that the tab is crashing, the parts just start visibly disappearing, and I can see other applications or my wallpaper behind it. When a youtube video is playing, the sound will keep going (without issue) even after the video stops and eventually disappears. I can reproduce this problem by having a youtube video playing in a tab, closing my laptop to idle it, and reopening it and logging back in. Doing so ensures this issue happens immediately, but the issue will still occur at other times, with or without a youtube video playing (that's just what I use to test the issue as per my example given).

Going through existing articles, I followed the steps in this one: https://support.mozilla.org/en-US/questions/1275189 since my issue seemed similar to theirs. Restarting Firefox in safe mode did indeed stop the issue! Then, I followed the steps to diagnose if it was an extension or hardware acceleration. (I use the default theme so that's not the issue.)

Disabling hardware acceleration didn't solve the problem. Okay, maybe it's not that, I'll turn off the (only) extension I have... And that didn't work either. I turned off hardware acceleration and my extensions, and the issue is still being produced.

So, I'm trying to understand, if safe mode only deactivates extensions, themes and hardware acceleration, why does the issue go away in safe mode but persist in normal mode with all extensions and hardware acceleration turned off on the default theme?

Attached are images of the "unloading" issue. Any help would be appreciated.

I was randomly getting the BSOD in Win 10 Pro 64b. Message said the error was "Unexpected Kernel Mode Trap". No external devices were connected, no new software had been installed, all drivers looked good. RAM was replaced (16GB). After looking at event viewer I saw that Firefox was running in all events. I uninstalled Firefox and it seems problem has stopped. Is this common, do I just need to re-install Firefox????

Thanks, KL

Until-- I leave Firefox or reboot the computer and the favorites are no longer available. If I do the same thing in Chrome, it remembers the preferences at all times, including after rebooting. Is there a way to make Firefox work as well as Chrome on this issue?

hi, i just installed ubuntu 20.04 LTS. I am not running any extensions or add-ons, just default settings. I can't play any youtube video that is considered 'live'. I can watch any other video on youtube, however. For the 'live' videos, I get a message: 'Your browser can't play this video, learn more' And when I click learn more, it says my browser is up to date. I tried streaming other videos from websites like crunchyroll.com and none work. I followed some suggestions to clear cache, turn on video/audio settings, etc. but nothing is working. Please assist. thanks.

Hello dear supporters,

Since a few Days I cannot reach any website. Or sometimes Websites Doesn’t load completely and get stucked. Or sometimes there is a reduced layout loading on the websites I want to go to _ more like in html mode.

different errores occur Browsing with Firefox:

SSL_ERROR_HANDSHAKE_FAILURE_ALERT SSL_ERROR_BAD_MAC_READ The wlan connection is stable - as in can Go in the Internet with other devices.

And the problem also occurs with other browers . Additional Info: (Also the Connection to the email servers communicates a problem with SSL: Failed to send the message. SSL has received an entry with invalid message authentication code. The settings for smtp.1and1.de must be corrected. ... then Every once in a while I can send messages )

Could you please help me to fix the problem with Firefox as I am in home office, like many of us, and working gets difficult like this.

Thank you Silvia

Hello everyone, 3 weeks ago I have started to face random crashes and no responding at all from my browser. Even though I have the latest version of Firefox but nothing seems to work well and I don't know the reason since it doesn't give me crash reports. In addition I didn't install any suspicious add-ons or external plugins since the problem had accrued.

Thanks in advance.

I am just not able to access sites related to CFA Institute, rest I am able to do. If I try to browse any of the site related to that, I am getting: 'Server Not Found", as window heading and below the description looks like this:

Hmm. We’re having trouble finding that site.

We can’t connect to the server at cfasocietyindia.org.

If that address is correct, here are three other things you can try:

   Try again later.
   Check your network connection.
   If you are connected but behind a firewall, check that Firefox has permission to access the Web.

I have tried every possible outcome, but not able to solve this. Hence if anyone can help on this, that would be great. Attaching a screenshot for a better refrence
